It is screewed into the driver's side head, between the first 2 spark plugs
Defective temperature sensor or bad gauge
Thermostat stuck open or no stat at all. Faulty temp sensor or Gauge.
Temp sensor for the gauge.
probably the sensor
THE temp sending unit 4 the inside gauge usally has 1 wire & the sending unit 4 the Computer has 2 wires.
look under the throttle body on the front of the engine there s a sensor with 3 wires going to it that is the engine coolant temperature sensor
Bad gauge and/or coolant temp sensor The coolant temp sensor doesn't control the gauge. There is a sensor in the head on the driver's side that controls the gauge. It is fairly easy to get to, probably one of the only things on a 4th gen. lol
The temp sending unit for the temp gauge is located on the drivers side of the engine between cylinders 3 and 5 spark plugs.
The coolant gauge temp sensor is a one wire sensor located on the right rear of the engine block.
Defective temperature gauge or defective temperature sensor?
Test gauge function with a mechanical gauge to get actual engine temp.
Could be you have a temp sensor for the ECM and a temp sender for the gauge. The gauge sender generally has one wire attached to it. The temp sensor generally has two wires attached to it. Perhaps you changed the wrong one.
